About this map

Gibson Reservoir dominates the northern landscape of this Rocky Mountain front survey, where the waters of the Sun River are impounded against the sheer rising face of the Sawtooth Range. The area is characterized by dramatic elevation shifts, from the low flats of Palmer Flats to the high summits of Allan Mountain and Elephant Head. A complex network of drainages including Lange Creek and Benchmark Creek carve through the Patricks Basin, illustrating the primitive character of the Lewis and Clark National Forest and the adjacent Bob Marshall Wilderness.

Human presence is concentrated near the dam at the Gibson Overlook Electronic Site and the historic Gibson Lake Lodge, while the interior remains a domain of trails and geological landmarks. Significant vertical features like the Black Reef and the deep Elbow Gorge highlight the area's role within the Sun River Game Refuge, where the topography dictates movement and settlement patterns along the eastern edge of the Continental Divide.
